Are Plug-In Solar kits easy to install?
Installing a Plug-In Solar kit requires NO experience, and is a simple plug and play assembly. You don’t need to be a qualified electrician, just a ‘skilled person’ . You can install your Plug-In Solar kit in the GARDEN, on the PATIO, SHED, PERGOLA, WORKSHOP, GARAGE, STABLE, BEACH HUT, SUMMER HOUSE, OFFICE or HOUSE roof. Anywhere with a mains grid connection. It’s up to you.
The Plug-In Solar Advantage
With standard Solar PV kits, electricity generation is dependent on the panel that is performing the worst. These types of systems will will not perform well with panels that are oriented in multiple directions or if panel shading is an issue.
Our Plug-In Solar Kits use Micro-Inverters to take full advantage of the production capability of each individual solar panel, regardless of shade or orientation to the sun. This ensures each panel can produce the maximum power and is not affected by the performance of another panel in the array.
The Plug-In Solar System is flexible, and modular so you can design a kit to fit your current budget and energy needs, and expand it later as you wish. The system is completely modular, meaning if you want to add more panels, or a solar battery, this can be simply achieved.
Plug-In Solar Kits are also Energy Storage Ready, meaning a battery system can easily be added to our kits using the Enphase AC Battery Storage Module.

The Enphase Envoy Gateway Monitoring Unit
The Enphase Envoy is an integral component of the Enphase Microinverter System, and is required for all Plug-In Solar Kits over 800W, in order to ensure compliance with the UK’s G98 Regulations. The Enphase Envoy allows you to monitor each individual solar panel in your installation, via the Enphase Enlighten App. More information about the Enphase Envoy can be seen here: Enphase Envoy
The Tile/Slate Roof Mount Kit

These are warrantied for 10 years. Please let us know the type of Tile/Slate you have on your roof at the time of placing an order.
The Plug-In Solar Connection Unit
The 3.5kW (3500W) Plug In Solar Kit includes two Plug-In Solar Connection Units, which are used to connect the solar to the mains grid. The solar can be connected as part of a ring main, as a spur from a ring main or on their own radial circuit. The switch is 13A, Double Pole and ensures the solar can be isolated from the rest of the grid if necessary, as required by the regulations. Please note: The maximum number of Enphase Micro-Inverters that can be connected through a single Plug-In Solar Connection Unit is ten, due to the amperage, so it is required that this kit is split between two connection units.
All components within the Plug In Solar kit comply fully with the G98 requirements and have MCS certifications, where applicable. All certifications/warranties available on request.
